Kev siv loj ntawm ethylene glycol yog ib qho tshuaj tiv thaiv kab mob hauv cov khoom ua kom txias, piv txwv li, tsheb thiab cov tshuab cua txias uas yog tso lub chiller lossis cov neeg ua haujlwm huab cua sab nraud lossis yuav tsum txias hauv qab qhov dej khov. Hauv geothermal cua sov / cua txias tshuab, ethylene glycol yog cov kua uas thauj cov cua sov los ntawm kev siv lub twj tso kua mis geothermal. Cov ethylene glycol yog nce lub zog los ntawm qhov chaw (lub pas dej, dej hiav txwv, dej zoo) los yog dissipates cua sov rau lub dab dej, nyob ntawm seb lub system puas siv rau cua sov los yog txias.
Ntshiab ethylene glycol muaj lub peev xwm kub ntawm ib nrab ntawm cov dej. Yog li, thaum muab kev tiv thaiv khov thiab qhov kub nce ntxiv, ethylene glycol txo qis lub peev xwm kub ntawm cov dej sib xyaw nrog rau cov dej ntshiab. A 1: 1 sib tov los ntawm huab hwm coj muaj peev xwm kub txog li 3140 J / (kg·°C) (0.75 BTU / (lb·°F)), peb lub hlis twg ntawm cov dej ntshiab, yog li yuav tsum tau nce cov nqi ntws hauv tib- qhov system sib piv nrog dej.

Siv cov extractant, xws li hlau, cobalt, tooj liab ntsev, diphenylcarbamide dihydrazine complex extraction. Rau kev sib cais ntawm lithium chloride hauv alkali hlau chlorides. |
Kev sib xyaw ntawm ethylene glycol nrog dej muab cov txiaj ntsig ntxiv rau kev ua kom txias thiab tshuaj tiv thaiv kab mob, xws li tiv thaiv corrosion thiab acid degradation, nrog rau inhibiting kev loj hlob ntawm feem ntau microbes thiab fungi.Mixtures ntawm ethylene glycol thiab dej yog qee zaum tsis raug xa mus rau hauv kev lag luam. glycol concentrates, compounds, mixs, los yog daws.
Hauv kev lag luam yas, ethylene glycol yog ib qho tseem ceeb ua ntej rau polyester fibers thiab resins. Polyethylene terephthalate, siv los ua lub raj mis yas rau cov dej qab zib, yog npaj los ntawm ethylene glycol.
Cov khoom lag luam zoo, kom muaj nuj nqis txaus, kev xa khoom zoo, kev pabcuam zoo Nws muaj qhov zoo dua li cov amine zoo sib xws, ethanolamine, nyob rau hauv qhov siab dua yuav siv tau rau tib lub peev xwm corrosion. Qhov no tso cai rau cov refiners los txhuam hydrogen sulfide ntawm qis dua amine tus nqi nrog tsawg zog siv tag nrho.
